Do You Lilac My Mad Black Onyx?

i've been pretty obsessed with O.P.I. nail polishes recently, with the most random assortment of colors:


Do You Lilac It?


Mad as a Hatter (from the Alice in Wonderland Collection)


Black Onyx

and occasionally i take it to the next level with Essie Matte About You matte topcoat.

and as any beauty queen can tell you, O.P.I. really is the best.
the new Shrek collection is way too tempting.

what's your favorite nail color?
